HAP has no idea where each room is relative to the next one. You use the Wall and Ceiling Partition tab on the Space input window to define a shared wall next to a space that is unconditioned or at a different temperature. You define the Wall or Ceiling U-value between the two spaces and then you set the max and min temperatures for the neighboring space relative to two outdoor temperature extremes. HAP then linearly calculates the neighboring space’s current temperature at any point in time base on the outside weather conditions at that point in time.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>For an unconditioned or partially conditioned basement below your conditioned floor, you do a similar input using the Floor tab and setting it to Above Unconditioned Space.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Good luck.

I am having trouble understanding conceptually how HAP handles certain cooling loads. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In my case, I have two adjacent rooms, one of which is air conditioned to 68 deg F and 50% RH, and the other does not need any A/C, just ventilation. There are a few set of rooms at one end of the station and another set of rooms at the other end of the station. Some of the rooms need A/C whereas some others don’t.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In HAP, I haven’t been able to figure out, how to assign an order to the rooms. I would think this order is important to assess the heat transfer between the rooms correctly and correspondingly calculate the overall heat load.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In order to estimate the heat load, I would like to have an independent a/c system for each room that needs to be airconditioned. Hence, I am using 5 CAV’s to air condition 5 spaces (rooms) and I am also using 4 CAV’s to ventilation ( not A/C) to ventilate the 4 non-A/C rooms. Also, there are corridors and windows.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>As mentioned earlier, I haven’t been able to figure out how to arrange the rooms in an order and how to group them. In the space properties, I see a tab for Partitions. But, it allows for a maximum of 2 partitions only. I am not sure if this is the way to specify internal walls.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The tutorial only comes with 2 examples, that does not consider a case where the rooms are conditioned differently.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any suggestions would be greatly appreciated.<o:p></o:p></p><p class=MsoNormal><o:p>
